Sets the snapping lines to be based on the history pointsadjacentto the point with a given history index. The given index can be one beyond the ends of the current history (i.e., -1 or PointHistoryLength) to base the lines on the first/last points. The snap lines will be parallel to the plane axes. Useful for moving a point to be aligned with one of its neighbors.
